ASTM E2335-12

Standard Guide for Laboratory Monitors

SIGNIFICANCE AND USE
4.1 These guidelines are intended to enable a laboratory monitor to perform onsite assessments of laboratory facilities. Accepted facilities will then participate in an interlaboratory test protocol to establish precision and bias for a particular ASTM standard.  
4.2 This assessment is intended to determine that all of the participants have the necessary equipment, an understanding of the test method, and the minimum level of skill necessary to gather data which are to be used to establish precision and bias for the particular standard.  
4.3 This guide is not intended to be used as a tool to qualify or accredit laboratories to perform any tests. Refer to ISO/IEC 17025 and to the A2LA R101 Document for further guidance on accreditation requirements.
SCOPE
1.1 This guide provides a general outline, for use by a laboratory monitor, to assess the qualifications of a laboratory which has requested to participate in a specific ASTM interlaboratory test.  
1.2 The preliminary assessment is based on observations made before initiation of any interlaboratory tests.  
1.3 The subcommittee, which appoints the laboratory monitor, specifies the minimum requirements which an organization should meet to qualify as a participant for the interlaboratory test. If a pretest is to be included, see details in Section 13.  
1.4 This fire standard can not be used to provide quantitative measures.  
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory requirements prior to use.

INTRODUCTION
This guide is for use by laboratory monitors who observe interlaboratory testing performed by
participatingorganizationsthatvalidatethelegitimacyoftestmethodsandalsoestablishabaseofdata
fromwhichprecisionandbiasstatementsaretobewritten.Interlaboratorytestingisdonetodetermine
the validity of a test standard. Such testing requires diligence by adhering to the protocol established
for performing the test in order to minimize variability which often exists between laboratories.
Because laboratories differ in size, organization, management, personnel, facilities and environment
there is always a potential for introducing variability in test results.
Laboratory monitors confirm that the participating facilities adhere to the test protocol as closely as
possible, thereby improving the chances of a successful interlaboratory study. The laboratory monitor
observes and assesses but does not perform the functions of an auditor or trainer; the laboratory
monitor does not provide accreditation of a laboratory. Laboratory monitors should demonstrate
expertise in both the content and the intent of the test method. The laboratory monitor is responsible
to render a report to the appointing subcommittee. It is incumbent upon the laboratory monitor to
maintain objectivity when working with participating laboratories.
Full-scale product fire tests are expensive, especially full-scale tests of bedding and home
furnishings. The development of this standard is intended to ensure that the precision and bias
developed for E05 standards demonstrates a high level of statistical validity.
This guide does not contain procedures for analysis of the test data obtained from an interlaboratory
study. The user is directed to Practice E691, if the laboratory study includes six laboratories or more,
and to Practice E2653 if the number of laboratories in the interlaboratory study is at least three, but
less than six.
Using a laboratory monitor as part of an interlaboratory test program is optional. However, if a
monitor is used, all of the laboratories in the project are to be included.

it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version

INTRODUCTION
This guide is for use by laboratory monitors who observe interlaboratory testing performed by
participating organizations that validate the legitimacy of test methods and also establish a base of data
from which precision and bias statements are to be written. Interlaboratory testing is done to determine
the validity of a test standard. Such testing requires diligence by adhering to the protocol established
for performing the test in order to minimize variability which often exists between laboratories.
Because laboratories differ in size, organization, management, personnel, facilities and environment
